MAX GLASS, OF VIENNA, AUSTRIA-HUNGARY.

MEANS FOR INCREASING TENSION OF GASEOUS PROPELLANTS FOR TORPEDOES.

To all whom it may concern:

Be it known that I, MAX GLAss, a subject of the Emperor ofAustria-Hungary, and a resident of 176 Hadikgasse, Vienna,Austria-Hungary, have invented certain new and useful Improvements inMeans for I11- creasing the Tension of Gaseous Propellants forTorpedoes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to means for increasing the tension of gaseouspropellants for torpedoes, in which the propellant or motive fluid issupplied through a worm to be heated by means of a heating device. Inthe operation of torpedoes it is important that the propellant be heatedsuddenly and rapidly, and that the heating device occupy little space.To this end, according to this invention, the air is heated in anoptionally coiled pipe by a burner which the pipe surrounds and to whichgas generated from carbid is supplied.

One illustrative embodiment of the invention is represented by way ofexample in the accompanying drawing, wherein:

Figure l is a vertical section through the device in the plane AB inFig. 2, and Fig. 2 is a side elevation of the casing containing theworm, partly in section in the plane GD in Fig. 1.

Referring to the drawing, in a closed casing a secured on a partition a(Fig. 2) in the torpedo Z) is arranged the hot-air pipe d having theform of a double worm around an asbestos or other suitable burner 6, sothat the heat given ofl by the burner is well utilized. Air is suppliedfrom the airvessel (not shown) through pipe f (Fig. 1) to worm (Z andflows through pipe 9 to the motor (not shown).

Secured to the wall Z) of the torpedo is a carbid vessel h (Fig. 1)containing calcium carbid i which is either loose or in briquet form. Inthe latter event the briquet has preferably the shape of a sleeve inorder to Specification of Letters Patent.

oifer as large asurface as possible to the water used for generatingacetylene. Above the carbid vessel is a water tank Z closed by a valve70, the gas supply pipe m is connected above to said tank and opensbelow burner 6 into casing 0.

If the device is to be set working, valve is is opened by a vertical rod4?. arranged under it being lifted by a lever 79 which is fulcrumed on aplate 0 and moved either by the same device which, when discharging thetorpedo, starts the motor, or by hand by means of a suitable devicebefore the discharge. Rod 91. is held in its upper position and valve 76is held open by a spring-influenced catch 9 which engages in a notch 1"in plate 0, so that water can flow into the carbid vessel and the gaswhich is generated can escape through the tank. The gas passes throughpipe m to the chamber or space 8 in casing 0 and flows through anorifice t to the burner e. In chamber .9 the gas mixes with air enteringthrough holes in an annular pipe u. The used air flowing from the motorcan be supplied to this pipe u through channel o. The mixture of gas andair is ignited at a glow pill to of platinum-sponge arranged above asieve or piece of gauze a2 preventing the flame flashing back. The flameheats the burner rapidly and highly, and the burner delivers its heatsuddenly to the worm. The products of combustion are conducted awaythrough pipe 3 (Fig. 2).

Instead of being formed as a single or double spiral the hot-air pipe (2may be arranged in several adjacent spirals, in which event severalburners may be provided.

1. In a torpedo, means for increasing the tension of a gaseous drivingfluid, compris ing a coil through which said driving fluid passes, anacetylene burner arranged axially within said coil for heating the same,an acetylene generator mounted on the inner face of a wall of thetorpedo and means for feeding said burner therefrom, substantially asdescribed.

2. In a torpedo, means for increasing the tension of a gaseous drivingfluid, comprising a coil through which said driving fluid passes, anacetylene burner arranged within said coil for heating the same, anacetylene generator and means for feeding said burner In testimonywhereof I have signed my therefrom, sa1d generator comprlsmg a oarnameto this speclfioation, 1n the presence of bld receptacle, a superposedWater tank and two subsorlblng W1tnesses.
